First, games are interesting in themselves, as constructions of space, logic and ideas (games are "a kind of playground for the mind"); second, they are interesting in their potential effect on other realms.

Chatfield's emphasis on games' fecund variety, on the other hand, will be valuable to non-specialists: he writes evocatively not just about Grand Theft Auto but about indie gems such as Passage, where your quest is meaningless and you die after five minutes. His comparison of videogames to installation art, meanwhile, is striking, and he even manages to make World of Warcraft sound interesting – though his awed description of a particular sword as being "the length of a full-grown orc" is rather lovable nonsense to someone who doesn't know how long orcs grow.
